Abstract

Electronics from the Bottom Up seeks to bring a new perspective to electronic devices – one that is designed to help realize the opportunities that nanotechnology presents. Ever since the birth of solid-state physics, materials have been described in terms of average material parameters like the mobility, optical absorption coefficient, etc., which are then used as inputs to macroscopic device models. Although still widely used, even for modern nanostructured materials, we believe that this two-step approach is no longer adequate to address the problems of our day. An integrated approach that embeds new ways of thinking, emerging from current research on nanoscience, directly into the models used for non-equilibrium problems like nanoscale transistors, energy conversion devices and bio-sensors is needed. The objectives of this initiative are to define and disseminate the fundamentals of this novel viewpoint through a carefully coordinated collection of seminars, short courses and full-semester courses.

In This Workshop

Nanoelectronic devices are at the heart of today's powerful computers and are also of great interest for many emerging applications including energy conversion, sensing and alternative computing paradigms. Our objective, however, is not to discuss specific devices or...

This two-part lecture will provide an introduction to first-principles density functional theory based methods for simulation of materials, with a focus on determination of interatomic force constants and vibrational spectra of nano- structures and extended periodic materials.

These lectures focus on the application of the theories using the nanoelectronic modeling tools NEMO 1- D, NEMO 3-D, and OMEN to realistically extended devices. Topics to be covered are realistic resonant tunneling diodes, quantum dots, nanowires, and Ultra-Thin-Body Transistors.
